Typedefs | |
| typedef void(*) | DrawFunc(void *dest, u8 *src, s32 x, s32 y, s32 width, s32 height) |
| A blitter loaded into a work slot: draws a width by height picture at (x, y) on the canvas. | |
Functions | |
| STATIC_ASSERT (offsetof(struct SparkWork, canvasOrigin)==offsetof(struct BattleEffectWork, trackedCanvas.origin)) | |
| s32 | BattleFx_UpdateStarField (void) |
| u32 | BattleFx_UploadStarField (void) |
| s32 | BattleFx_InitializeStarField (s32 mode) |
| Starts a star field of the element mode (0 to 3, enum Element order): sixteen sparks on random rings and three rings 120 degrees apart. | |
| s32 | Graphics_ResetVramBlockAndReleaseHeapBlocks (s32 unused) |
| Ends a star field: clears BG2's tiles in character block 1, frees its blitters, canvas and work, turns BG2 off and removes both callbacks. | |
| s32 | Graphics_ScaleRgb555Clamped (u16 *source, u16 *destination, s32 scale, s32 count) |
| Copies count colours from source to destination, each channel scaled by scale (16.16, at most 1), and returns 0. | |
| void | BattleFx_PlayUnitElementEffect (s32 unitId, s32 element, s32 mode, s32 variant) |
| Plays a glow of the element about a unit, and returns when it is over. | |
| void | BattlePres_RestorePalette (void) |
| Copies the background's saved palette back undarkened, as the star field of BattleFx_PlayUnitElementEffect leaves it dark. | |
| void | Runtime_RemoveIrqHandlerSlot2 (void) |
| Removes the VCount interrupt's handler, as BattlePres_RunEntryTransition installs one; nothing calls it. | |

Starts a star field of the element mode (0 to 3, enum Element order): sixteen sparks on random rings and three rings 120 degrees apart.
Allocates the field's work (HEAP_SLOT_BATTLE_EFFECT) and a cleared 128 by 128 canvas (HEAP_SLOT_BATTLE_CANVAS), decodes the blue ring sheet into the work, loads the element's 64 colours over the first of BG palette RAM, sets BG2's affine parameters to no zoom, loads both blitters and adds BattleFx_UpdateStarField and BattleFx_UploadStarField. Also sets BattleBackgroundView.mode to 1. Called by BattleFx_PlayUnitElementEffect; Graphics_ResetVramBlockAndReleaseHeapBlocks undoes it.

Ends a star field: clears BG2's tiles in character block 1, frees its blitters, canvas and work, turns BG2 off and removes both callbacks.
Called by BattleFx_PlayUnitElementEffect once the field has played.

Copies count colours from source to destination, each channel scaled by scale (16.16, at most 1), and returns 0.
Called to darken the background's palette by BattlePresentation_SetPaletteLevel, BattleBackground_Load, BattleFx_PlayUnitElementEffect, the item staging (staging.c) and the effects' canvas (canvas.c).

Plays a glow of the element about a unit, and returns when it is over.
By mode: 0 the star field gathering on the unit while the background darkens (a cast), 1 the element streaks, 2 the element pillar at strength variant (a summon's power boost) and 3 the element burst (a Djinni set). Called with 0 by BattlePresentation_RunUnitTransition and BattlePres_RunPsynergyCast, with 1 by the latter, with 2 by BattleUnit_ProcessTurnEnd and with 3 by Battle_ProcessRoundEnd and BattleCommand_BuildPlan. Every mode first puts the background in mode 1 and opens window 0 over lines 16 to 135, with BG2 blended over the other layers; mode 0 leaves the background's palette and BattleWork.brightness darkened.
